Definitions
- the field of the invention generally relates to water and lighting displays, including those that involve unmanned aerial systems (UASs).
- UASs unmanned aerial systems
- these displays have involved lights that shine at different angles and change color.
- these lighting systems may be generally configured and attached to the ground or within a fountain basin. They may also be attached to ground-based structures such as stationary platforms, buildings or towers, tracks with carriages that run along the tracks and to which the lighting systems may be attached, buildings that may include mounts upon which the lighting systems may be attached or other structures.
- the lights in many of the foregoing configurations are often at or near ground level, which generally limits the location from which the light may emanate.
- the lights of other configurations listed above may be located higher, or may travel along tracks or cables or may rotate about an axis. But even with these types of structures, the lights are ultimately anchored to a location and/or may be bound in terms of their lighting coverage. This may limit the visual effects provided by the lighting system. That is, the lights may not be able to move in a certain direction or move in other manners such as rotation if those capabilities are outside of their design parameters.
- the current invention addresses the limitations and shortcomings of lighting assemblies and systems that are generally ground-based and that provide only limited configuration of providing light.
- UASs may add to or otherwise enhance the visual effects provided by the display.
- the UAS(s) may carry lighting systems so that lights may be shined at water or other features in the display from an elevated position.
- the UAS(s) may move thereby changing the position from which light is shined.
- the flight of the UAS(s) may in and of itself enhance the visual effects provided by the display.
- one or more UASs may be piloted or programmed to perform desired flight plans or choreographies.
- the choreography of the UAS(s) may be programmed to complement the direction and/or intensity of shooting water and/or lighting of a display. In this manner, the overall expression or visual effect of the display may be enhanced.
- the UAS(s) may provide lighting capability at high elevations relative to the water source without the need to construct supporting towers or other supports, such as unsightly and potentially dangerous scaffolding, or rely on attaching an elevated lighting system to a nearby building.
- the current invention provides a cost-savings benefit and provides greater flexibility to the manner in which lighting may be provided to a display or otherwise.

- UAS 10 may provide a movable lighting system located above the ground that may illuminate water displays or other structures from this elevated position.
- UAS 10 may include a lighting system 100 that may include lighting assemblies 110 that may shine one or more beams of light 600 onto water stream 512 that may emanate from nozzle 510 of water display 500 .
- UAS 10 with lighting system 100 and lighting assembly 110 may provide illumination to water stream 512 from unique perspectives and vantage points not attainable with ground-based lighting systems.
- UAS 10 may shine light downwardly or in some other direction.
- UAS 10 may be filled with lighting 100 is further described in U.S. Provisional Ser. No. 62/067,978, the contents of which are incorporated by reference as if fully set forth herein.
- UAS lighting system 100 may also shine one or more beams of light upon fog or water mist 516 that may exist in areas generally above and around water stream 512 , as well as on water droplets and water particles 514 that may generally fall from water stream 512 . Illuminating fog or mist 516 may provide an illuminated cloud effect, while illuminating water droplets 514 from above while they fall to the ground may result in a “raining light” visual effect.
- UAS lighting system 100 may also direct beams of light into basin 518 of water display 500 , or onto other structures that may be a part of water display 500 such as reflective sign 520 , boats (not shown), characters (not shown) or other structures.
- FIG. 1 shows a single UAS 10
- multiple UASs 10 may alternatively be used. This preferably provides further enhancement by elevated lighting systems 100 .
- the one or more UASs 10 may move as they shine light beam(s) 600 , which may also enhance the visual effects of display 500 .
- UASs 10 configured with lighting systems 100 may also perform lighting shows that may shine light onto the audience or onto other targets. This may resemble lighting shows that may be experienced at musical concerts, e.g., light shows involving lasers. In this embodiment, it is preferred that only unharmful lasers or lights be used, i.e., those that do not cause damage to human eyes.
- water stream 512 is depicted as a vertical water stream in FIG. 1 , it may be of any shape or type of water element such as a funnel, cone, fan, waterfall, water wall or other shape, and may be directed in any direction such as horizontal, at an angle or in other directions. Also, while the UAS 10 depicted in FIG. 1 as a multi-copter, other types of UASs may also be utilized.
- lighting assembly 110 as shown in FIG. 1 is generally depicted as a directional lighting assembly such as a spotlight, a laser or other type of directional light source, other types of lights and assemblies may be utilized.
- lighting assembly 110 may instead consist of a multi-directional light such as a bulb, a multi-directional array of LEDs or other type of light source.
- lighting assembly 110 may comprise of multiple spotlights or lasers that may shine in different directions, or a combination of multi-directional lighting assemblies, directional lighting assemblies and other light sources.
- lighting assembly 110 may shine light in a variety of directions including sideways, upward, downward or in any other direction.
- UAS lighting systems 100 that utilize light sources that may cause damage to human eyes may also include controls to avoid pointing these light sources at observers. To this end, GPS and suitable software may control the orientation of UAS 10 and lighting system 100 . Also, lighting assembly 110 may comprise lights that shine white light, lights that shine colored light, or lights that shine a combination of white light and colored light. UAS lighting system 100 may be used in lieu of other types of lighting systems, independently of other types of lighting systems or in combination with other types of lighting systems, e.g., ground based lighting systems.
- Ground based lighting systems are, by design, limited to illuminating a target from predefined vantage points that are limited by the design of the system. For example, a fixed ground based light may only illuminate a target from its physical position.
- a lighting system mounted to a carriage that my travel along a track or a wire may illuminate a target only from the positions along the track or wire, but may not illuminate a target from any other positions that are beyond the track or wire.
- a rotatable lighting system may illuminate a target from any angle of rotation that is available to it, but cannot illuminate a target from any other location.
- UAS lighting system 100 may illuminate a target from any location, height or angle to which UAS 10 may fly.
- UAS 10 may be flown to a position that is vertically above fountain 500 such that lighting system 100 may shine a light downward to illuminate fountain stream 512 from above.
- UAS 10 may be positioned at a different location, such as to the side of the same fountain stream 512 or to a different fountain stream 512 , such that it may illuminate fountain stream 512 from the side.
- these vantage points may not need to be predetermined, and no mounts, platforms, tracks or wires need to be pre-designed and constructed as would be necessary for a ground based system to achieve the same lighting results.
- shining light at an object or feature of display 500 such as water stream 512 , droplets 514 or mist 516 from different locations generally provides different visual effects. It is also preferred that decisions regarding the vantage points from which illumination occurs may be made in real-time by a show director, or from inputs or requests by remote operators, crowd consensus, online polling or any other suitable decision-making system. As such, the current invention provides for a dynamic and variable enhancement of the visual effects and expression provided by display 500 .
- UAS lighting system 100 may continuously illuminate one or more fountain streams 512 , while UAS 10 maneuvers to different positions about display 500 .
- UAS 10 with lighting system 100 may perform a spiral maneuver around a vertical fountain stream 512 , moving up and down while circling stream 512 , all the while illuminating the stream 512 .
- UAS 10 may be piloted or programmed to provide this choreography. This represents an advance over ground based lighting systems which require construction of a physical track or intricate cabling system with lighting carriages around fountain stream 512 . These tracks or cables require additional money and time to design and construct, and the physical nature of such a ground based lighting system may block the view of the fountain from the audience thus diminishing the aesthetic effect of the overall fountain display 500 .
- UAS 10 may fly close and/or also pass through water streams 512 , water particles 514 or water mist 516 as part of a choreographed lighting performance. As shown in FIG. 2 , lighted UASs 10 flying in proximity to water stream 512 may result in a dramatic and entertaining visual effect. In this situation, it may be preferable for UAS 10 to be configured with water resistant brushless motors that may be capable of providing thrust to UAS 10 without the need for elaborate waterproofing efforts. Other considerations relating to UASs 10 with lighting systems 100 flying directly through or in close proximity to water streams 512 are discussed in more detail below.
- water display 500 may be illuminated by lighting systems positioned high above the ground and/or display 500 without the need for tall platforms, towers or other structures that would otherwise be needed to support elevated lighting.
- the ability to illuminate from high elevations also avoids the need to attach lighting to nearby buildings or other structures that may be nearby. And even if an existing structure such as a neighboring building were available to support lighting, the height, angle and position from which the lighting could illuminate water display 500 may be limited by the location and height of the building.
- the light beam would degrade as the distance between the light source and display 500 increases. This in turn could limit the ability to adequately illuminate water display 500 or provide enhanced visual effects. Additionally, it may be desired to focus beams of light on separate in-line water streams 512 that may be intermittent or spaced separately or obstructed by other water streams from the line of sight position of the ground based light.
- UAS(s) 10 as in the current invention preferably avoids the foregoing issues. As such, the current invention's use of UAS(s) 10 provides cost-savings, reduced logistical requirements, and greater flexibility to the manner in which lighting may be provided.
- the current invention may render display 500 relatively self-contained and/or transportable.
- UASs 10 and their lighting systems 100 are not limited to the physical location of a neighboring building or dedicated light-support structure. Instead, UASs 10 and their lighting systems, including their power supplies are self-contained and require no design and construction of physical structures with associated power sources. Accordingly, to the extent that display 500 is intended to be packed up and transported to various locations, UASs 10 facilitate this capability.
- UASs 10 and their lighting systems 100 provide additional advantages regarding the illumination of display 500 .
- no land need be purchased, leased or otherwise dedicated to a lighting system 100 and no building or other land use permits associated with buildings or structures are required.
- no significant obstruction of view of water display 500 will occur since no additional structures need be built.
- UASs 10 configured with lighting systems 100 of the current invention may be employed to provide the elevated lighting necessary for the event at a budget and schedule within reason. Accordingly, as noted above, the current invention may facilitate display 500 traveling from city to city, thus eliminating the requirement to construct new ground based lighting systems, lease space or obtain legal building permits for such traveling events.
- UAS 10 or a fleet of UASs 10 may be used with different displays 500 at various locations as desired.
- UASs 10 may simultaneously illuminate water display 500 or other type of feature.
- multiple UASs 10 each configured with lighting systems 100 , may be choreographed to illuminate water or other display features as part of the overall visual effect of display 500 .
- two UASs 10 with lighting systems 100 may perform a spiral maneuver around a vertical fountain stream or streams 512 together.
- UASs 10 may be positioned apart from each other by 180 degrees such that each UAS 10 may illuminate opposite sides of vertical water stream 512 during the maneuver, moving up and down while encircling and illuminating stream 512 .
- Each UAS lighting system 100 may also utilize a different color of light thus adding to the visual effect.
- UASs 10 may be used in the current invention and is not intended to limit the scope of the invention. Indeed, the manner in which UASs 10 may be used with or engage display 10 are almost limitless.
- UASs 10 may perform entirely off the ground, they pose minimal obstruction of display 500 to the audience. This is a significant advance when considering the potential obstructions that would be posed by the tracks or wires with lighting carriages that would need to be constructed to provide this visual effect with a ground-based lighting system. While the above example described two UASs 10 used in combination, any number of UASs 10 may be used. In addition, multiple UASs 10 may be used to illuminate water display 500 independently of each other and not in a choreographed fashion.
- UAS lighting systems 100 do not require the design and construction of ground based platforms or mounts, the use of UAS lighting systems 100 may allow for much greater flexibility in the modification of water streams 512 within water display 500 , as well as the illumination of these targets. For instance, if water display 500 were to be enlarged to include the addition of several newly built water elements 512 , there may be no need to design and construct new lighting systems to accommodate the modification since these new water streams 512 may be illuminated by a re-choreographed fleet of UAS lighting systems 100 .
- the illumination of water streams 512 may be readily modified.
- the intensity of the illumination provided may be adjusted to accommodate changes in the surroundings, e.g., where shadows are created by a newly-built neighboring building.
- the fleet of UAS lighting systems 100 may be modified with no ground construction necessary.
- lighting assemblies 110 may be changed to include a higher intensity light source, or another UAS lighting system 100 may be added to provide additional illumination.
- lighting system 100 may be integrated into or otherwise attached to UAS 10 using mount(s) 700 .
- mount(s) 700 may include brackets, bolts, locks, latches or other attachment means to secure and position lighting system 100 relative to UAS 10 .
- lighting system(s) 100 may be connected to UAS body 12 and/or arm(s) 14 .
- lighting assemblies 110 are preferably connected to UAS 10 so that lighting assembly 110 may shine light upon a desired target while UAS 10 flies, hovers or is located in a desired location(s).
- Mount 700 may secure lighting system 100 and lighting assembly 110 in a fixed position or may allow lighting system 100 and lighting assembly 110 to be controllably moved side to side, up and down, at an angle, rotated about an axis or in any other direction. These movements may allow a target to be more precisely illuminated. This may also allow lighting system 100 to write words, create illustrations or produce other images on a surface.
- Controllable mount 700 may be preprogrammed, manually controlled by the pilot of UAS 10 , controlled by an automated control system or controlled by other means.
- Each UAS 10 configured with lighting system 100 may be controlled individually or in combination with other UAS lighting systems 100 by a pilot in real time, or by a computer or other type of automated controller. Aspects of UAS 10 and lighting system 100 that may be controlled may include: 1) the position and flight coordinates of each UAS 10 with respect to the illumination targets, other UASs 10 in the fleet and any other nearby structures, 2) the position and orientation of lighting system 100 with respect to UAS 10 and illumination targets, 3) the lighting sequences to illuminate the targets in relation to the position of each UAS 10 , 4) the position of UASs 10 in relation to observers for safety purposes and 5) any other aspect that may need to be controlled to allow the illumination of water display 500 by UAS lighting systems 100 .
- UAS(s) 10 may include an onboard controller with software to control its flight, or software may be used in a controller that transmits control signals to UAS(s) 10 . Wherever this software resides, it may include pre-programmed choreography sequences to allow for fully automated shows to take place with minimal human intervention. Conversely, the software may allow for the manual orchestration of UAS lighting systems 100 . In addition, the software may allow for a combination of automated pre-programmed shows that may be manually altered or otherwise manually controlled in real time as desired. UASs 10 may include a GPS device so that its coordinates may be used by the software to control its next movements and to ensure UASs 10 remain in their intended flight path.
- UAS 10 may include one or more cameras, transmitters or other mechanisms that may determine positional information and relay the physical location of UASs 10 to a computer or controller so that the ensuing movement of UAS 10 may be appropriately controlled.
- the GPS, camera or other means to determine location may act in a control loop to continuously or semi-continuously correct, adjust or alter the location or flight of UAS 10 .
- lighting system 100 may be attached to UAS 10 using an extendable arm 720 .
- FIG. 5A depicts extendable arm 720 in a generally retracted configuration
- FIG. 5B depicts extendable arm 720 in a generally extended configuration.
- Extendable arm may be preferred for certain UAS 10 maneuvers. For example, while UAS 10 may physically pass through water streams 512 , water particles 514 and/or water mist 516 without the threat of damage to UAS 10 or the disruption of its flying capabilities, it may be preferable for propellers 16 of UAS 10 to avoid physical contact with the foregoing.
- arm 720 may be extended to allow light 100 to pass through stream(s) 512 , droplets 514 or mist 516 while propellers remain above. This may be desirable when, for example, light 110 is intended to fly through high velocity water streams 512 to avoid the force of these streams 512 disrupting the flying capabilities of UAS 10 or otherwise altering its position or course.
- UAS 10 may be safely positioned near stream 512 , and then extend extendable arm 720 may be extended such that lighting system 100 may be moved to a position that is now closer to, or possibly in physical contact with, water steam 512 .
- arm 720 may include segments 722 , 724 that may, for example, be nested together while in the retracted position of FIG. 5A , but which may extend and lengthen arm 720 in the extended position in FIG. 5B .
- Other means to lengthen arm 720 may also be used.
- FIGS. 5A and 5B depict extendable arm 720 as extending in a generally downward direction
- extendable arm 720 may extend in generally sideways direction, a generally upward direction or in any other direction. It should be noted that extended arm 720 may be in a retracted position as depicted in FIG. 5A for UAS 10 takeoff and landing such that lighting system 100 does not interfere with these operations.
- a benefit of extendable arm 720 is that by positioning lighting system 100 closer to display 500 , the illumination of water stream 512 , droplets 514 or mist 516 may be higher in intensity and more vibrant in color due to the optical properties of light shining through water at close range, while still keeping distance between stream 512 and propellers 16 . In sum, enhanced lighting effect may be unachieved.
- UAS 10 may be positioned directly above vertical water stream 512 and may lower lighting system 100 directly into the top portion of water stream 512 to illuminate it from within for a dramatic visual effect. UAS 10 may also hover or fly in a path that is just above the surface of water in water basin 518 such that lighting system 100 may be submerged into basin 518 , thus “painting” colored light onto the water's surface.
- Enabling lighting system 100 to come into physical contact with water of stream 512 , water droplets 514 or water mist 516 may also provide the additional benefit of cooling lighting system 100 .
- lighting assemblies may be submerged or in close proximity to the water in basin 518 of water display 500 and may be cooled by the water. These assemblies may also be submerged or in close proximity to water steams 512 or in the path of water particles 514 for cooling purposes as well.
- UAS lighting systems 100 may also benefit from the cooling properties of the water display elements.
- extendable arm 720 is depicted in FIG. 5B as telescoping, it may also extend through the use of foldable arms or sections, or may extend by other means. In addition, there may be configurations where the arm may not be extendable but instead may be of a fixed length and may still provide the benefits described above. For example, a balanced rod (not shown) may project from UAS 10 to position lighting assembly 110 into water stream 512 , water particles 514 , water mist 516 , water basin 518 or into other elements of fountain 500 .
- lighting system 100 may be attached to UAS 10 by a retractable cable assembly 730 .
- FIG. 6A depicts retractable cable assembly 730 in a generally retracted or recoiled configuration and
- FIG. 6B depicts retractable cable assembly 730 in a generally extended configuration.
- UAS 10 configured with retractable cable assembly 730 may safely position itself beyond water stream 512 , and then may lower lighting system 100 by extending cables 732 of retractable cable assembly 730 such that lighting system 100 may be moved to a position that is closer to, or immersed in, water steam 512 .
- FIG. 6B depicts the use of three extendable cables 732 to secure and lower lighting system 100 but other numbers of cables or other tethers 732 may be used.
- FIG. 6B also depicts the cables 732 configured in a straight line to support lighting system 100 , but other configurations may be utilized such as three cables that form a triangular cross-section, four cables that form a square cross-section or other configurations.
- Cables 732 of retractable cable assembly 730 may be similar to each other or have different cross-sectional configurations. While FIG. 6B depicts three cables 732 generally parallel to each other, retractable cables 732 may be configured at different angles with respect to each other. As with extendable arm 720 , it may be preferable for retractable cable assembly 730 to be in a generally retracted or recoiled position as depicted in FIG. 6A for UAS 10 takeoff and landing such that lighting system 100 does not interfere with these operations. Alternatively, as with the operation of aircraft that tow banners and streamers, cables 732 may be laid out in careful order to enable takeoffs and landing, or snared and dropped by UASs 10 already in flight.
- retractable cable assembly 730 may have the ability to lower lighting system 100 further down and away from the body 12 of UAS 10 when compared to extendable arm 720 . This may be due to fact that coiled cables may take up less physical space on a payload of UAS 10 compared to extendable sections of extendable arm 720 , and because of this, more length of coiled cables may be carried by UAS 10 .
- UAS 10 may position itself vertically above water stream 512 and may lower lighting system 100 and lighting assembly 110 into the top of water stream 512 by uncoiling retractable cable assembly 730 . Because UAS 10 may be able to lower lighting system 100 to a greater distance below its body 12 , lighting system 100 and lighting assembly 110 may be lowered further into water stream 512 .
- UAS 10 may be able to position itself high enough above water stream 512 to be generally out of the primary viewing area of the audience, and may lower lighting system 100 and lighting assembly 110 from the top of water stream 512 to a position generally towards the bottom of water stream 512 .
- lighting assembly 110 comprise of a multidirectional light such that the outer circumference of water stream 512 may be illuminated evenly from the inside as lighting assembly 110 travels up and down the inside of water stream 512 . This may create a dramatic and entertaining water display effect that may be difficult to achieve with ground base lighting systems.
- extendable arm 720 and/or retractable cable assembly 730 have the ability to position lighting systems 100 at varying distances from UAS 10 .
- lighting system 100 be removable from UAS 10 so that it may be attached when needed and removed when not. This may allow UAS 10 to be fitted with the lighting system 100 for use in providing light to a water display 500 or other structure, and to then be utilized without lighting system 100 for other purposes.
- lighting system 100 may be replaced with a releasable payload mounting system 716 as shown in FIGS. 7A and 7B .
- the removable payload may comprise many different types of items.
- the payload may comprise a light that is dropped from UAS 10 while in flight during a performance so that the falling light may form part of the overall performance of display 500 .
- the payload may be a pyrotechnic feature that ignites after being dropped during a performance.
- the payload may be a weighted object that is released so that it splashes in pool 518 of display 500 .
- payload mounting system 716 may be programmed to disengage at a desired time in the performance as part of a choreographed event.
- payload system 716 may be programmed to disengage when UAS 10 is located at a particular location defined by GPS coordinates and/or altitude.
- UAS 10 may include a female mounting component that may be attached to body 12 or other component of UAS 10
- lighting system 100 may include a male mounting component 712 .
- male component 712 may be secured to female component 710 such that lighting system 100 may be securely attached to UAS 10 for use in lighting a water display as described above.
- male mount 712 may be disengaged from female mount 710 so that lighting system 100 separates from UAS 10 as depicted in FIG. 7B . While this specification describes releasable mounting system 716 as having male and female components 712 , 710 , and while FIGS. 7A and 7B show mounting system 710 and mounting system 712 as female and male components, respectively, other releasable mounting systems 716 are within the scope of the current invention.
- mounting system 716 component 710 need not be male and component 712 need not be female. Instead, their configurations may be reversed.
- mounting system 716 may comprise other locking mechanisms, bolts, screws, latches and other components that may securely mate to each other and attach lighting system 100 to UAS 10 .
- other payloads may be securely attached to UAS 10 using similar mounting systems 716 for use with other applications.
- lighting system 100 with male mounting system 712 may also be securely attached to a different UAS 10 configured with a female mounting system 710 .
- Releasable mounting system 716 may also be utilized with extendable arm 720 depicted in FIGS. 5A and 5B , in the above embodiment regarding retractable cable assembly 730 depicted in FIGS. 6A and 6B , and/or in other embodiments described throughout this specification.
- extendable arm 720 configured with lighting system 100 may be removably attached to UAS 10 utilizing releasable mounting system 716 as described above.
- retractable cable assembly 730 configured with lighting system 100 may be removably attached to UAS 10 utilizing releasable mounting system 716 as well.
- lighting system 100 may be removably attached to either extendable arm 720 or retractable cable assembly 730 in a similar manner.
- lighting system 100 may be a fully self-contained item with rechargeable battery or power source and control systems, and thus allow for rapid swapping of depleted systems for fully charged electrical lighting units.
- UAS lighting system 100 may include projector assembly 112 that may project images or video onto a target such as adjacent water stream 512 (e.g., FIGS. 1 and/or 8 ) or water curtain that forms water wall 518 within fountain 500 ( FIG. 8 ).
- UAS 10 configured with projector assembly 112 may project an image or video onto water wall 518 such that the image or video may be viewable by an audience.
- adjacent water streams or wall 518 comprise a waterfall, a funnel shaped stream or another type of water stream or water feature that may have a width sufficiently wide to allow an image or video to be projected onto it and be viewed by an audience.
- UAS 10 equipped with projector assembly 112 may project images or video onto water wall 518 and an audience may view the images or video from generally the same side of water wall 518 . This may be similar to a movie theater where the audience and the projector are positioned on the same side of the viewing screen. In another configuration, an audience may be generally positioned on the opposite side of water wall 518 compared to UAS 10 such that images and video projected by projector assembly 112 may project onto and pass through water wall 518 such that they are viewable on the opposite side. Both of these configurations may add a very dramatic and exciting element to a lighted water display show.
- UAS 10 A with lighting system 100 may shine light onto a separate UAS 10 B that may be configured with a “shadow puppet” shape 120 such that the shape 120 may cast a shadow onto a surface behind it such as a water wall 516 , water particles 514 , water fog 516 , a screen or other type of target or surface.
- Water wall 516 may comprise a series of adjacent water streams 512 , a waterfall, a funnel shaped stream, or another type of water stream that may have a width sufficiently wide to allow the shadow cast by shape 120 onto water wall 516 to be viewable by an audience.
- FIG. 9 depicts shadow puppet shape 120 as generally hanging below UAS 10
- shape 120 may be positioned to the side, above or in any other position or configuration with UAS 10 .
- shape 120 may be integrated with UAS 10 such that UAS 10 and shape 120 together may cast the shadow.
- shape 120 may be a static shape as depicted in FIG. 9 , or may have the ability to dynamically change such that the shadow it may cast may also change.
- shape 120 may change from the numerals that represent the current year to the shape of the numerals that represent the New Year. For instance, if the current year was 2014 and the New Year was 2015, shape 120 , and the shadow cast by shape 120 , may change from the numerals 2014 to the numerals 2015 to reflect the changing of the year.
- UAS 10 may include tether 99 that may couple UAS 10 to a ground-based station 90 or operator. Tether 99 may provide safety by preventing UAS 10 from flying beyond areas deemed safe for UAS 10 or from simply flying off. For example, should UAS 10 malfunction and crash, tether 99 may be of a chosen length at any point in time during a light show that it may not allow UAS 10 to enter or otherwise crash into an area where an audience may exist.
- Tether 99 may be shortened and/or lengthened in real time during the show to account for the position of UAS 10 such that UAS 10 does not enter an unsafe location.
- This control may be manual or may be provide by a computer or other type of controller.
- Tether 99 may also provide power and other control signals to UAS 10 . This may eliminate the need for an on-board power source, or may avoid the need to recharge or replace batteries or other power sources that may be utilized by UAS 10 . Furthermore, the duty cycle of signal provided by tether 99 may remain constant.
- tether 99 may be that it may allow UAS 10 to be fitted with more light assemblies 100 because no battery or other on-board power source may be needed. In other words, more light assemblies 100 may be added because the increase in weight they represent may be offset by the subtracted weight of the battery.
- Tether 99 may also transmit electrical signals to control UAS 10 , as opposed to the radio frequency signals that are typically used with untethered UASs 10 . This is a benefit because radio signals may be interfered with by nearby electrical appliances and/or third parties. To this end, tether 99 allows two way communication between ground station 90 or operator, and UAS 10 . That is, tether 99 may also support signals from UAS 10 to the ground. Such signals may include position data and status of lights or other on-board appliances.
- UAS 10 may weigh less than a specified amount to avoid being subject to otherwise pertinent regulations. This may eliminate restrictive regulations imposed by governmental agencies upon the commercial usage of drones. Such commercial UAS regulations may include the following: 1) the UASs may only be flown within the sight of the operator, 2) the UASs may only fly up to 100 miles per hour, 3) operators of the drones must be at least 17 years of age and 4) operators of the drones must pass an aeronautics test and be vetted by the Transportation Security Administration.
- UAS 10 depicted in FIG. 10 may avoid the time and costs associated with addressing these restrictions.
- tether 99 may include water line 98 that may run from a ground based water supply to UAS 10 .
- water may be pumped from the ground to UAS 10 so that water may be launched into the air through water nozzle 96 configured with UAS 10 from a position off the ground.
- the resulting elevated water streams 514 may create an exciting upside-down fountain effect.
- These streams 514 may not necessarily be illuminated, or may be illuminated by lighting system 100 residing on the same UAS 10 that may be providing the off-the-ground water stream 514 , by a different lighting system 100 configured on a different UAS 10 , by a ground based lighting system or by other lighting means.
- Providing off-the-ground water streams 514 may offer a whole new aesthetic dimension to the water stream features of water display 500 .
- UAS 10 may be configured with bucket 94 , shovel or other type of container that may hold water and that may allow UAS 10 to carry and drop water from positions off the ground.
- Water container 94 may be filled with water prior to take-off or may have the ability to refill as necessary by being submerged into water basin 518 as depicted in FIG. 12C , or be refilled by other water streams 512 (not shown) or other water sources.
- UAS 10 configured with water container 94 may hover in the air while holding the water, and may then release the water into the air as depicted in FIG. 12A to form off the ground water stream 514 .
- water streams created by dropping water may not necessarily be illuminated, or may be illuminated by lighting system 100 residing on the same UAS 10 that may be providing the off the ground water stream, by a different lighting system 100 configured on a different UAS 10 , by a ground based lighting system or by other lighting means.
- UAS 10 may be configured to direct the generally downward stream of air that is created by its propellers 16 (often referred to as downwash or propwash) onto the water surface, into areas around water streams 512 , or to other areas, to clear any undesired fog or mist that may exist.
- UAS 10 may include air rudders, channels, or other guide structures that may direct its propwash in a desired and controllable direction. UAS 10 may then be positioned such that its propwash may disperse fog or mist from water display 500 as necessary.
- UAS 10 may be configured with an additional fan or air blower unit that may achieve the desired result.
- the propwash from UAS 10 or the air stream from an additional air blower unit may be used to reshape water streams 512 mid-air, creating new shapes of blown water and mist.
- four UASs 10 positioned in equal quadrants around vertical water stream 512 may each channel air streams into water steam 512 at a slightly upward angle in order to create upward shooting spikes of water and mist resulting in a “floating crown”.
- UASs 10 may be configured with cameras and memory units to record and save images and video footage of water display 500 from perspectives and vantage points previously unattainable.
- UASs 10 may also be configured with broadcast units to transmit recorded images or video to a ground station which may project the footage onto a screen or relay it to a large video monitor (such as a Jumbotron) to be viewed by an audience.
- UAS 10 may have the ability to bypass ground station and broadcast recorded footage directly to a video monitor equipped with a receiver unit to display the footage to the audience in real time.
- footage from UAS 10 as described above may also be broadcast on the Internet in real time for audiences around the world to view.
- UAS 10 configured with a camera, memory and broadcast capability may position itself directly above water display 500 while recording and broadcasting its footage. Video footage from this vantage point may then be displayed in real time onto a large screen that is viewable to the audience of water display 500 , as well as broadcast on the Internet to a global audience, thus giving both audiences a never before seen top-down perspective of water display 500 . It can be seen that such video footage or still images may also be recorded and stored for future viewing by similar or different audiences.
Abstract
Description
- This application claims the benefit of U.S. Provisional Application No. 62/271,775, filed Dec. 28, 2015, the contents of which are incorporated herein by reference.
- The field of the invention generally relates to water and lighting displays, including those that involve unmanned aerial systems (UASs).
- In recent years, elaborate water and lighting displays have been developed. For example, the fountains in front of the Bellagio Hotel have been seen and enjoyed by millions of people from around the world. Other displays have been developed that continue to make innovative use of water and light.
- Regarding the lighting elements, these displays have involved lights that shine at different angles and change color. In addition, these lighting systems may be generally configured and attached to the ground or within a fountain basin. They may also be attached to ground-based structures such as stationary platforms, buildings or towers, tracks with carriages that run along the tracks and to which the lighting systems may be attached, buildings that may include mounts upon which the lighting systems may be attached or other structures.
- However, the lights in many of the foregoing configurations are often at or near ground level, which generally limits the location from which the light may emanate. The lights of other configurations listed above may be located higher, or may travel along tracks or cables or may rotate about an axis. But even with these types of structures, the lights are ultimately anchored to a location and/or may be bound in terms of their lighting coverage. This may limit the visual effects provided by the lighting system. That is, the lights may not be able to move in a certain direction or move in other manners such as rotation if those capabilities are outside of their design parameters.
- Accordingly, there is a need in the field of water and lighting displays for lights that may move in various directions and in different manners, and that may emit light from above the ground. There is also a need for manners in which such lighting may be used with water and/or light displays to provide enhanced visual effects.
- The current invention addresses the limitations and shortcomings of lighting assemblies and systems that are generally ground-based and that provide only limited configuration of providing light.
- In a first aspect of the invention, the use of UASs with water and lighting displays is described. To this end, UASs may add to or otherwise enhance the visual effects provided by the display. For example, the UAS(s) may carry lighting systems so that lights may be shined at water or other features in the display from an elevated position. Furthermore, the UAS(s) may move thereby changing the position from which light is shined. Still further, the flight of the UAS(s) may in and of itself enhance the visual effects provided by the display.
- In another aspect of the invention one or more UASs may be piloted or programmed to perform desired flight plans or choreographies. To this end, the choreography of the UAS(s) may be programmed to complement the direction and/or intensity of shooting water and/or lighting of a display. In this manner, the overall expression or visual effect of the display may be enhanced.
- In another aspect of the invention, the UAS(s) may provide lighting capability at high elevations relative to the water source without the need to construct supporting towers or other supports, such as unsightly and potentially dangerous scaffolding, or rely on attaching an elevated lighting system to a nearby building. In this manner, the current invention provides a cost-savings benefit and provides greater flexibility to the manner in which lighting may be provided to a display or otherwise.

For example, some of the lighting systems, configurations of the lighting systems, and applications of the lighting systems of the current invention may assume different configurations and may utilize different types and numbers of UASs. Furthermore, one or more different types of lighting systems, configurations or applications may be used. The current invention is now described with reference to the figures. Similar reference numerals may be used throughout the figures to denote the same or similar components.
- The current invention generally involves the use of one or more UASs to enhance the lighting and other visual effects that may be provided by displays, such as water and lighting displays. For example, as shown in
FIG. 1 , UAS 10 may provide a movable lighting system located above the ground that may illuminate water displays or other structures from this elevated position. In the embodiment ofFIG. 1 ,UAS 10 may include alighting system 100 that may includelighting assemblies 110 that may shine one or more beams of light 600 ontowater stream 512 that may emanate fromnozzle 510 ofwater display 500. In this configuration,UAS 10 withlighting system 100 andlighting assembly 110 may provide illumination towater stream 512 from unique perspectives and vantage points not attainable with ground-based lighting systems. At the same or different time, anotherlighting assembly 110 onUAS 10 may shine light downwardly or in some other direction. The manner in whichUAS 10 may be filled withlighting 100 is further described in U.S. Provisional Ser. No. 62/067,978, the contents of which are incorporated by reference as if fully set forth herein. -
UAS lighting system 100 may also shine one or more beams of light upon fog orwater mist 516 that may exist in areas generally above and aroundwater stream 512, as well as on water droplets andwater particles 514 that may generally fall fromwater stream 512. Illuminating fog ormist 516 may provide an illuminated cloud effect, while illuminatingwater droplets 514 from above while they fall to the ground may result in a “raining light” visual effect. In addition,UAS lighting system 100 may also direct beams of light intobasin 518 ofwater display 500, or onto other structures that may be a part ofwater display 500 such asreflective sign 520, boats (not shown), characters (not shown) or other structures. - While
FIG. 1 shows asingle UAS 10,multiple UASs 10 may alternatively be used. This preferably provides further enhancement byelevated lighting systems 100. Furthermore, the one ormore UASs 10 may move as they shine light beam(s) 600, which may also enhance the visual effects ofdisplay 500. -
UASs 10 configured withlighting systems 100 may also perform lighting shows that may shine light onto the audience or onto other targets. This may resemble lighting shows that may be experienced at musical concerts, e.g., light shows involving lasers. In this embodiment, it is preferred that only unharmful lasers or lights be used, i.e., those that do not cause damage to human eyes. - While
water stream 512 is depicted as a vertical water stream inFIG. 1 , it may be of any shape or type of water element such as a funnel, cone, fan, waterfall, water wall or other shape, and may be directed in any direction such as horizontal, at an angle or in other directions. Also, while theUAS 10 depicted inFIG. 1 as a multi-copter, other types of UASs may also be utilized. - It should be noted that while
lighting assembly 110 as shown inFIG. 1 is generally depicted as a directional lighting assembly such as a spotlight, a laser or other type of directional light source, other types of lights and assemblies may be utilized. For example,lighting assembly 110 may instead consist of a multi-directional light such as a bulb, a multi-directional array of LEDs or other type of light source. In addition,lighting assembly 110 may comprise of multiple spotlights or lasers that may shine in different directions, or a combination of multi-directional lighting assemblies, directional lighting assemblies and other light sources. Thus,lighting assembly 110 may shine light in a variety of directions including sideways, upward, downward or in any other direction. -
UAS lighting systems 100 that utilize light sources that may cause damage to human eyes may also include controls to avoid pointing these light sources at observers. To this end, GPS and suitable software may control the orientation ofUAS 10 andlighting system 100. Also,lighting assembly 110 may comprise lights that shine white light, lights that shine colored light, or lights that shine a combination of white light and colored light.UAS lighting system 100 may be used in lieu of other types of lighting systems, independently of other types of lighting systems or in combination with other types of lighting systems, e.g., ground based lighting systems. - There are various benefits of an elevated
UAS lighting system 100. Ground based lighting systems are, by design, limited to illuminating a target from predefined vantage points that are limited by the design of the system. For example, a fixed ground based light may only illuminate a target from its physical position. A lighting system mounted to a carriage that my travel along a track or a wire may illuminate a target only from the positions along the track or wire, but may not illuminate a target from any other positions that are beyond the track or wire. A rotatable lighting system may illuminate a target from any angle of rotation that is available to it, but cannot illuminate a target from any other location. - Advantageously, however,
UAS lighting system 100 may illuminate a target from any location, height or angle to whichUAS 10 may fly. For example,UAS 10 may be flown to a position that is vertically abovefountain 500 such thatlighting system 100 may shine a light downward to illuminatefountain stream 512 from above. Alternatively,UAS 10 may be positioned at a different location, such as to the side of thesame fountain stream 512 or to adifferent fountain stream 512, such that it may illuminatefountain stream 512 from the side. Besides the advantage of unique vantage locations from which to illuminate, these vantage points may not need to be predetermined, and no mounts, platforms, tracks or wires need to be pre-designed and constructed as would be necessary for a ground based system to achieve the same lighting results. - In any event, it is preferred that shining light at an object or feature of
display 500, such aswater stream 512,droplets 514 ormist 516 from different locations generally provides different visual effects. It is also preferred that decisions regarding the vantage points from which illumination occurs may be made in real-time by a show director, or from inputs or requests by remote operators, crowd consensus, online polling or any other suitable decision-making system. As such, the current invention provides for a dynamic and variable enhancement of the visual effects and expression provided bydisplay 500. - As another example of this enhancement,
UAS lighting system 100 may continuously illuminate one or more fountain streams 512, whileUAS 10 maneuvers to different positions aboutdisplay 500. For example,UAS 10 withlighting system 100 may perform a spiral maneuver around avertical fountain stream 512, moving up and down while circlingstream 512, all the while illuminating thestream 512. To perform this flight path and lighting effect,UAS 10 may be piloted or programmed to provide this choreography. This represents an advance over ground based lighting systems which require construction of a physical track or intricate cabling system with lighting carriages aroundfountain stream 512. These tracks or cables require additional money and time to design and construct, and the physical nature of such a ground based lighting system may block the view of the fountain from the audience thus diminishing the aesthetic effect of theoverall fountain display 500. - As another example of this enhancement,
UAS 10 may fly close and/or also pass throughwater streams 512,water particles 514 orwater mist 516 as part of a choreographed lighting performance. As shown inFIG. 2 , lightedUASs 10 flying in proximity towater stream 512 may result in a dramatic and entertaining visual effect. In this situation, it may be preferable forUAS 10 to be configured with water resistant brushless motors that may be capable of providing thrust toUAS 10 without the need for elaborate waterproofing efforts. Other considerations relating toUASs 10 withlighting systems 100 flying directly through or in close proximity towater streams 512 are discussed in more detail below. - With the current invention,
water display 500 may be illuminated by lighting systems positioned high above the ground and/ordisplay 500 without the need for tall platforms, towers or other structures that would otherwise be needed to support elevated lighting. The ability to illuminate from high elevations also avoids the need to attach lighting to nearby buildings or other structures that may be nearby. And even if an existing structure such as a neighboring building were available to support lighting, the height, angle and position from which the lighting could illuminatewater display 500 may be limited by the location and height of the building. Furthermore, the light beam would degrade as the distance between the light source and display 500 increases. This in turn could limit the ability to adequately illuminatewater display 500 or provide enhanced visual effects. Additionally, it may be desired to focus beams of light on separate in-line water streams 512 that may be intermittent or spaced separately or obstructed by other water streams from the line of sight position of the ground based light. - Furthermore, significant design and construction costs would probably be incurred to install and support the lighting in a manner to adequately illuminate
display 500. Additional costs and logistics to provide electrical power for such lighting would also be required. Regardless whether this power came from local power lines, from the power system of the associated building, from dedicated power generators, from battery packs or from other sources of power, this requirement would also add significant expense to the construction of the elevated lighting system. If the building or structure were not owned by the same owner ofwater display 500, additional costs and complex negotiations may be required to lease or purchase a portion of the structure necessary for the installation. Also, legal building permits may be necessary for the allowance of such physical and electrical construction thus adding additional time and expense. - The use of UAS(s) 10 as in the current invention preferably avoids the foregoing issues. As such, the current invention's use of UAS(s) 10 provides cost-savings, reduced logistical requirements, and greater flexibility to the manner in which lighting may be provided.
- Furthermore, the current invention may render
display 500 relatively self-contained and/or transportable. For example,UASs 10 and theirlighting systems 100 are not limited to the physical location of a neighboring building or dedicated light-support structure. Instead,UASs 10 and their lighting systems, including their power supplies are self-contained and require no design and construction of physical structures with associated power sources. Accordingly, to the extent that display 500 is intended to be packed up and transported to various locations,UASs 10 facilitate this capability. - The use of
UASs 10 and theirlighting systems 100 provide additional advantages regarding the illumination ofdisplay 500. For example, no land need be purchased, leased or otherwise dedicated to alighting system 100, and no building or other land use permits associated with buildings or structures are required. Furthermore, no significant obstruction of view ofwater display 500 will occur since no additional structures need be built. - Due to the expense, time commitment, lease and/or permits that may be necessary to design and build ground based lighting systems as discussed above, these structures may typically tend to be permanent in nature. Accordingly, it may not make financial sense to construct such structures at such high costs for temporary events or displays. However, the use of
UASs 10 configured withlighting systems 100 of the current invention may be employed to provide the elevated lighting necessary for the event at a budget and schedule within reason. Accordingly, as noted above, the current invention may facilitatedisplay 500 traveling from city to city, thus eliminating the requirement to construct new ground based lighting systems, lease space or obtain legal building permits for such traveling events. Alternatively,UAS 10, or a fleet ofUASs 10 may be used withdifferent displays 500 at various locations as desired. - Another embodiment of the current invention involving multiple UASs is now described with reference to
FIG. 3 . As shown,UASs 10 may simultaneously illuminatewater display 500 or other type of feature. In this embodiment,multiple UASs 10, each configured withlighting systems 100, may be choreographed to illuminate water or other display features as part of the overall visual effect ofdisplay 500. For example, twoUASs 10 withlighting systems 100 may perform a spiral maneuver around a vertical fountain stream orstreams 512 together. In this example, as depicted inFIG. 3 ,UASs 10 may be positioned apart from each other by 180 degrees such that eachUAS 10 may illuminate opposite sides ofvertical water stream 512 during the maneuver, moving up and down while encircling and illuminatingstream 512. EachUAS lighting system 100 may also utilize a different color of light thus adding to the visual effect. - The foregoing is just one example of how
UASs 10 may be used in the current invention and is not intended to limit the scope of the invention. Indeed, the manner in whichUASs 10 may be used with or engagedisplay 10 are almost limitless. - It should also be noted that because
UASs 10 may perform entirely off the ground, they pose minimal obstruction ofdisplay 500 to the audience. This is a significant advance when considering the potential obstructions that would be posed by the tracks or wires with lighting carriages that would need to be constructed to provide this visual effect with a ground-based lighting system. While the above example described twoUASs 10 used in combination, any number ofUASs 10 may be used. In addition,multiple UASs 10 may be used to illuminatewater display 500 independently of each other and not in a choreographed fashion. - The increased flexibility in the visual effects of
display 500 with the use ofUASs 10 is also shown as follows. BecauseUAS lighting systems 100 do not require the design and construction of ground based platforms or mounts, the use ofUAS lighting systems 100 may allow for much greater flexibility in the modification ofwater streams 512 withinwater display 500, as well as the illumination of these targets. For instance, ifwater display 500 were to be enlarged to include the addition of several newly builtwater elements 512, there may be no need to design and construct new lighting systems to accommodate the modification since these new water streams 512 may be illuminated by a re-choreographed fleet ofUAS lighting systems 100. - In addition, the illumination of
water streams 512 may be readily modified. For example, the intensity of the illumination provided may be adjusted to accommodate changes in the surroundings, e.g., where shadows are created by a newly-built neighboring building. In this situation, the fleet ofUAS lighting systems 100 may be modified with no ground construction necessary. In this example,lighting assemblies 110 may be changed to include a higher intensity light source, or anotherUAS lighting system 100 may be added to provide additional illumination. - The manners in which single and multi-UAS 10 embodiments may be configured is now further described. In one embodiment, as shown in
FIG. 4 ,lighting system 100 may be integrated into or otherwise attached toUAS 10 using mount(s) 700. In this embodiment, mount(s) 700 may include brackets, bolts, locks, latches or other attachment means to secure andposition lighting system 100 relative toUAS 10. To this end, lighting system(s) 100 may be connected toUAS body 12 and/or arm(s) 14. In any event,lighting assemblies 110 are preferably connected toUAS 10 so thatlighting assembly 110 may shine light upon a desired target whileUAS 10 flies, hovers or is located in a desired location(s). -
Mount 700 may securelighting system 100 andlighting assembly 110 in a fixed position or may allowlighting system 100 andlighting assembly 110 to be controllably moved side to side, up and down, at an angle, rotated about an axis or in any other direction. These movements may allow a target to be more precisely illuminated. This may also allowlighting system 100 to write words, create illustrations or produce other images on a surface.Controllable mount 700 may be preprogrammed, manually controlled by the pilot ofUAS 10, controlled by an automated control system or controlled by other means. - Each
UAS 10 configured withlighting system 100 may be controlled individually or in combination with otherUAS lighting systems 100 by a pilot in real time, or by a computer or other type of automated controller. Aspects ofUAS 10 andlighting system 100 that may be controlled may include: 1) the position and flight coordinates of eachUAS 10 with respect to the illumination targets,other UASs 10 in the fleet and any other nearby structures, 2) the position and orientation oflighting system 100 with respect toUAS 10 and illumination targets, 3) the lighting sequences to illuminate the targets in relation to the position of eachUAS 10, 4) the position ofUASs 10 in relation to observers for safety purposes and 5) any other aspect that may need to be controlled to allow the illumination ofwater display 500 byUAS lighting systems 100. - UAS(s) 10 may include an onboard controller with software to control its flight, or software may be used in a controller that transmits control signals to UAS(s) 10. Wherever this software resides, it may include pre-programmed choreography sequences to allow for fully automated shows to take place with minimal human intervention. Conversely, the software may allow for the manual orchestration of
UAS lighting systems 100. In addition, the software may allow for a combination of automated pre-programmed shows that may be manually altered or otherwise manually controlled in real time as desired.UASs 10 may include a GPS device so that its coordinates may be used by the software to control its next movements and to ensureUASs 10 remain in their intended flight path. Alternatively,UAS 10 may include one or more cameras, transmitters or other mechanisms that may determine positional information and relay the physical location ofUASs 10 to a computer or controller so that the ensuing movement ofUAS 10 may be appropriately controlled. To this end, the GPS, camera or other means to determine location may act in a control loop to continuously or semi-continuously correct, adjust or alter the location or flight ofUAS 10. - In another embodiment, as shown in
FIGS. 5A and 5B ,lighting system 100 may be attached toUAS 10 using anextendable arm 720.FIG. 5A depictsextendable arm 720 in a generally retracted configuration, andFIG. 5B depictsextendable arm 720 in a generally extended configuration. Extendable arm may be preferred forcertain UAS 10 maneuvers. For example, whileUAS 10 may physically pass throughwater streams 512,water particles 514 and/orwater mist 516 without the threat of damage toUAS 10 or the disruption of its flying capabilities, it may be preferable forpropellers 16 ofUAS 10 to avoid physical contact with the foregoing. Accordingly,arm 720 may be extended to allow light 100 to pass through stream(s) 512,droplets 514 ormist 516 while propellers remain above. This may be desirable when, for example, light 110 is intended to fly through high velocity water streams 512 to avoid the force of thesestreams 512 disrupting the flying capabilities ofUAS 10 or otherwise altering its position or course. However, withextendable arm 720,UAS 10 may be safely positioned nearstream 512, and then extendextendable arm 720 may be extended such thatlighting system 100 may be moved to a position that is now closer to, or possibly in physical contact with,water steam 512. - As shown in
FIGS. 5A, 5B ,arm 720 may include segments 722, 724 that may, for example, be nested together while in the retracted position ofFIG. 5A , but which may extend and lengthenarm 720 in the extended position inFIG. 5B . Other means to lengthenarm 720 may also be used. - While
FIGS. 5A and 5B depictextendable arm 720 as extending in a generally downward direction,extendable arm 720 may extend in generally sideways direction, a generally upward direction or in any other direction. It should be noted thatextended arm 720 may be in a retracted position as depicted inFIG. 5A forUAS 10 takeoff and landing such thatlighting system 100 does not interfere with these operations. - A benefit of
extendable arm 720 is that by positioninglighting system 100 closer to display 500, the illumination ofwater stream 512,droplets 514 ormist 516 may be higher in intensity and more vibrant in color due to the optical properties of light shining through water at close range, while still keeping distance betweenstream 512 andpropellers 16. In sum, enhanced lighting effect may be unachieved. - As additional examples,
UAS 10 may be positioned directly abovevertical water stream 512 and may lowerlighting system 100 directly into the top portion ofwater stream 512 to illuminate it from within for a dramatic visual effect.UAS 10 may also hover or fly in a path that is just above the surface of water inwater basin 518 such thatlighting system 100 may be submerged intobasin 518, thus “painting” colored light onto the water's surface. - Enabling
lighting system 100 to come into physical contact with water ofstream 512,water droplets 514 orwater mist 516 may also provide the additional benefit of coolinglighting system 100. With typical ground based lighting systems, lighting assemblies may be submerged or in close proximity to the water inbasin 518 ofwater display 500 and may be cooled by the water. These assemblies may also be submerged or in close proximity to water steams 512 or in the path ofwater particles 514 for cooling purposes as well. By enablingUAS lighting systems 100 to come into physical contact withwater streams 512,water particles 514 orwater mist 516, or to be submerged intowater basin 518 while in flight,UAS lighting system 100 may also benefit from the cooling properties of the water display elements. - While
extendable arm 720 is depicted inFIG. 5B as telescoping, it may also extend through the use of foldable arms or sections, or may extend by other means. In addition, there may be configurations where the arm may not be extendable but instead may be of a fixed length and may still provide the benefits described above. For example, a balanced rod (not shown) may project fromUAS 10 to positionlighting assembly 110 intowater stream 512,water particles 514,water mist 516,water basin 518 or into other elements offountain 500. - In another embodiment as shown in
FIGS. 6A and 6B ,lighting system 100 may be attached toUAS 10 by aretractable cable assembly 730.FIG. 6A depictsretractable cable assembly 730 in a generally retracted or recoiled configuration andFIG. 6B depictsretractable cable assembly 730 in a generally extended configuration. Similar toextendable arm 720 described above,UAS 10 configured withretractable cable assembly 730 may safely position itself beyondwater stream 512, and then may lowerlighting system 100 by extendingcables 732 ofretractable cable assembly 730 such thatlighting system 100 may be moved to a position that is closer to, or immersed in,water steam 512. - The use of multiple
extendable cables 732 may be preferable whenlighting system 100 is in a generally lowered position in order to provide additional stabilization and to help minimize the rotation or other movement oflighting system 100 relative toUAS 10.FIG. 6B depicts the use of threeextendable cables 732 to secure andlower lighting system 100 but other numbers of cables orother tethers 732 may be used.FIG. 6B also depicts thecables 732 configured in a straight line to supportlighting system 100, but other configurations may be utilized such as three cables that form a triangular cross-section, four cables that form a square cross-section or other configurations. -
Cables 732 ofretractable cable assembly 730 may be similar to each other or have different cross-sectional configurations. WhileFIG. 6B depicts threecables 732 generally parallel to each other,retractable cables 732 may be configured at different angles with respect to each other. As withextendable arm 720, it may be preferable forretractable cable assembly 730 to be in a generally retracted or recoiled position as depicted inFIG. 6A forUAS 10 takeoff and landing such thatlighting system 100 does not interfere with these operations. Alternatively, as with the operation of aircraft that tow banners and streamers,cables 732 may be laid out in careful order to enable takeoffs and landing, or snared and dropped byUASs 10 already in flight. - This retractable cable embodiment provides the benefits described above in connection with the
extendable arm 720. In addition however,retractable cable assembly 730 may have the ability to lowerlighting system 100 further down and away from thebody 12 ofUAS 10 when compared toextendable arm 720. This may be due to fact that coiled cables may take up less physical space on a payload ofUAS 10 compared to extendable sections ofextendable arm 720, and because of this, more length of coiled cables may be carried byUAS 10. - Using the same example as described above,
UAS 10 may position itself vertically abovewater stream 512 and may lowerlighting system 100 andlighting assembly 110 into the top ofwater stream 512 by uncoilingretractable cable assembly 730. BecauseUAS 10 may be able to lowerlighting system 100 to a greater distance below itsbody 12,lighting system 100 andlighting assembly 110 may be lowered further intowater stream 512. - With enough cable length available from
retractable cable assembly 730,UAS 10 may be able to position itself high enough abovewater stream 512 to be generally out of the primary viewing area of the audience, and may lowerlighting system 100 andlighting assembly 110 from the top ofwater stream 512 to a position generally towards the bottom ofwater stream 512. In this example it may be preferable thatlighting assembly 110 comprise of a multidirectional light such that the outer circumference ofwater stream 512 may be illuminated evenly from the inside aslighting assembly 110 travels up and down the inside ofwater stream 512. This may create a dramatic and entertaining water display effect that may be difficult to achieve with ground base lighting systems. - It should be noted that different desired lighting effects and
choreographed UAS 10 movements may requirelighting system 100 to be positioned at different distances belowbody 12 ofUAS 10. Accordingly, it may be preferable thatextendable arm 720 and/orretractable cable assembly 730 have the ability to positionlighting systems 100 at varying distances fromUAS 10. - In the embodiments described above, it is preferred that
lighting system 100 be removable fromUAS 10 so that it may be attached when needed and removed when not. This may allowUAS 10 to be fitted with thelighting system 100 for use in providing light to awater display 500 or other structure, and to then be utilized withoutlighting system 100 for other purposes. - For example,
lighting system 100 may be replaced with a releasablepayload mounting system 716 as shown inFIGS. 7A and 7B . The removable payload may comprise many different types of items. For example, the payload may comprise a light that is dropped fromUAS 10 while in flight during a performance so that the falling light may form part of the overall performance ofdisplay 500. As another example, the payload may be a pyrotechnic feature that ignites after being dropped during a performance. In another example, the payload may be a weighted object that is released so that it splashes inpool 518 ofdisplay 500. - To control the time when such item falls,
payload mounting system 716 may be programmed to disengage at a desired time in the performance as part of a choreographed event. Alternatively,payload system 716 may be programmed to disengage whenUAS 10 is located at a particular location defined by GPS coordinates and/or altitude. -
System 716 may allow different payloads to be mounted ontoUAS 10 using various securing mechanisms. For example, as depicted inFIGS. 7A and 7B ,UAS 10 may include a female mounting component that may be attached tobody 12 or other component ofUAS 10, andlighting system 100 may include amale mounting component 712. With this configuration as depicted inFIG. 7A ,male component 712 may be secured tofemale component 710 such thatlighting system 100 may be securely attached toUAS 10 for use in lighting a water display as described above. - When lighting
system 100 is not needed or when it is desired thatUAS 10 be used for other purposes,male mount 712 may be disengaged fromfemale mount 710 so thatlighting system 100 separates fromUAS 10 as depicted inFIG. 7B . While this specification describes releasable mountingsystem 716 as having male andfemale components FIGS. 7A and 7B show mountingsystem 710 and mountingsystem 712 as female and male components, respectively, other releasable mountingsystems 716 are within the scope of the current invention. - Furthermore, in mounting
system 716,component 710 need not be male andcomponent 712 need not be female. Instead, their configurations may be reversed. Alternatively, mountingsystem 716 may comprise other locking mechanisms, bolts, screws, latches and other components that may securely mate to each other and attachlighting system 100 toUAS 10. Also, whenlighting system 100 is not attached toUAS 10, other payloads may be securely attached toUAS 10 usingsimilar mounting systems 716 for use with other applications. Also,lighting system 100 withmale mounting system 712 may also be securely attached to adifferent UAS 10 configured with afemale mounting system 710. -
Releasable mounting system 716 may also be utilized withextendable arm 720 depicted inFIGS. 5A and 5B , in the above embodiment regardingretractable cable assembly 730 depicted inFIGS. 6A and 6B , and/or in other embodiments described throughout this specification. For instance,extendable arm 720 configured withlighting system 100 may be removably attached toUAS 10 utilizingreleasable mounting system 716 as described above. Similarly,retractable cable assembly 730 configured withlighting system 100 may be removably attached toUAS 10 utilizingreleasable mounting system 716 as well. In addition,lighting system 100 may be removably attached to eitherextendable arm 720 orretractable cable assembly 730 in a similar manner. - There are various benefits of
removable lighting assemblies 100, payloads or other items that may be attached and detached fromUAS 10. First, ifUAS 10 becomes damaged or requires maintenance,lighting system 100 may be readily removed from the damagedUAS 10 and installed onto adifferent UAS 10 configured withfemale mounting system 710. This may limit any downtime ofdisplay 500 that includes UAS(s) 10 sincelighting system 100 may readily be redeployed on adifferent UAS 10. Also, becauselighting system 100 may be removed fromUAS 10 when not in use, other payloads may then be attached toUAS 10 for other purposes, soUAS 10 may be utilized for other projects. This may allow for several projects to share the expense of the purchasing, leasing, renting, maintaining and operatingUAS 10 sinceUAS 10 may be configured to support each project with different payloads at any given time. Additionally,lighting system 100 may be a fully self-contained item with rechargeable battery or power source and control systems, and thus allow for rapid swapping of depleted systems for fully charged electrical lighting units. - In another embodiment depicted in
FIG. 8 , but also with reference to other figures,UAS lighting system 100 may includeprojector assembly 112 that may project images or video onto a target such as adjacent water stream 512 (e.g.,FIGS. 1 and/or 8 ) or water curtain that formswater wall 518 within fountain 500 (FIG. 8 ).UAS 10 configured withprojector assembly 112 may project an image or video ontowater wall 518 such that the image or video may be viewable by an audience. It may be preferable that adjacent water streams orwall 518 comprise a waterfall, a funnel shaped stream or another type of water stream or water feature that may have a width sufficiently wide to allow an image or video to be projected onto it and be viewed by an audience. - In one configuration,
UAS 10 equipped withprojector assembly 112 may project images or video ontowater wall 518 and an audience may view the images or video from generally the same side ofwater wall 518. This may be similar to a movie theater where the audience and the projector are positioned on the same side of the viewing screen. In another configuration, an audience may be generally positioned on the opposite side ofwater wall 518 compared toUAS 10 such that images and video projected byprojector assembly 112 may project onto and pass throughwater wall 518 such that they are viewable on the opposite side. Both of these configurations may add a very dramatic and exciting element to a lighted water display show. - In another embodiment as depicted in
FIG. 9 ,UAS 10A withlighting system 100 may shine light onto aseparate UAS 10B that may be configured with a “shadow puppet”shape 120 such that theshape 120 may cast a shadow onto a surface behind it such as awater wall 516,water particles 514,water fog 516, a screen or other type of target or surface.Water wall 516 may comprise a series of adjacent water streams 512, a waterfall, a funnel shaped stream, or another type of water stream that may have a width sufficiently wide to allow the shadow cast byshape 120 ontowater wall 516 to be viewable by an audience. - While
FIG. 9 depictsshadow puppet shape 120 as generally hanging belowUAS 10,shape 120 may be positioned to the side, above or in any other position or configuration withUAS 10. In addition,shape 120 may be integrated withUAS 10 such thatUAS 10 andshape 120 together may cast the shadow. Also,shape 120 may be a static shape as depicted inFIG. 9 , or may have the ability to dynamically change such that the shadow it may cast may also change. In one example, to celebrate a New Year's Eve event,shape 120 may change from the numerals that represent the current year to the shape of the numerals that represent the New Year. For instance, if the current year was 2014 and the New Year was 2015,shape 120, and the shadow cast byshape 120, may change from the numerals 2014 to thenumerals 2015 to reflect the changing of the year. - In another embodiment as depicted in
FIG. 10 ,UAS 10 may include tether 99 that may coupleUAS 10 to a ground-basedstation 90 or operator. Tether 99 may provide safety by preventingUAS 10 from flying beyond areas deemed safe forUAS 10 or from simply flying off. For example, should UAS 10 malfunction and crash, tether 99 may be of a chosen length at any point in time during a light show that it may not allowUAS 10 to enter or otherwise crash into an area where an audience may exist. - Accordingly, it may be necessary for the length of tether 99 to be shortened and/or lengthened in real time during the show to account for the position of
UAS 10 such thatUAS 10 does not enter an unsafe location. This control may be manual or may be provide by a computer or other type of controller. Tether 99 may also provide power and other control signals toUAS 10. This may eliminate the need for an on-board power source, or may avoid the need to recharge or replace batteries or other power sources that may be utilized byUAS 10. Furthermore, the duty cycle of signal provided by tether 99 may remain constant. - An advantage of tether 99 may be that it may allow
UAS 10 to be fitted with morelight assemblies 100 because no battery or other on-board power source may be needed. In other words, morelight assemblies 100 may be added because the increase in weight they represent may be offset by the subtracted weight of the battery. - Tether 99 may also transmit electrical signals to control
UAS 10, as opposed to the radio frequency signals that are typically used withuntethered UASs 10. This is a benefit because radio signals may be interfered with by nearby electrical appliances and/or third parties. To this end, tether 99 allows two way communication betweenground station 90 or operator, andUAS 10. That is, tether 99 may also support signals fromUAS 10 to the ground. Such signals may include position data and status of lights or other on-board appliances. - In addition, by utilizing tethers 99 so that
UAS 10 need not carry a battery and/or other payload,UAS 10 may weigh less than a specified amount to avoid being subject to otherwise pertinent regulations. This may eliminate restrictive regulations imposed by governmental agencies upon the commercial usage of drones. Such commercial UAS regulations may include the following: 1) the UASs may only be flown within the sight of the operator, 2) the UASs may only fly up to 100 miles per hour, 3) operators of the drones must be at least 17 years of age and 4) operators of the drones must pass an aeronautics test and be vetted by the Transportation Security Administration. By utilizing tether 99 and thus avoiding such regulations,UAS 10 depicted inFIG. 10 may avoid the time and costs associated with addressing these restrictions. - In another embodiment as depicted in
FIG. 11 , tether 99 may include water line 98 that may run from a ground based water supply toUAS 10. As such, water may be pumped from the ground toUAS 10 so that water may be launched into the air throughwater nozzle 96 configured withUAS 10 from a position off the ground. The resultingelevated water streams 514 may create an exciting upside-down fountain effect. Thesestreams 514 may not necessarily be illuminated, or may be illuminated bylighting system 100 residing on thesame UAS 10 that may be providing the off-the-ground water stream 514, by adifferent lighting system 100 configured on adifferent UAS 10, by a ground based lighting system or by other lighting means. Providing off-the-ground water streams 514 may offer a whole new aesthetic dimension to the water stream features ofwater display 500. - Furthermore, in another embodiment as depicted in
FIGS. 12A, 12B and 12C ,UAS 10 may be configured withbucket 94, shovel or other type of container that may hold water and that may allowUAS 10 to carry and drop water from positions off the ground.Water container 94 may be filled with water prior to take-off or may have the ability to refill as necessary by being submerged intowater basin 518 as depicted inFIG. 12C , or be refilled by other water streams 512 (not shown) or other water sources. - As depicted in
FIG. 12B ,UAS 10 configured withwater container 94 may hover in the air while holding the water, and may then release the water into the air as depicted inFIG. 12A to form off theground water stream 514. Similar to off the ground water streams 514 in relation to the use of water lines and tethers 99, water streams created by dropping water may not necessarily be illuminated, or may be illuminated bylighting system 100 residing on thesame UAS 10 that may be providing the off the ground water stream, by adifferent lighting system 100 configured on adifferent UAS 10, by a ground based lighting system or by other lighting means. In this fashion,multiple UASs 10 equipped withcontainers 94 may drop water in unison in a choreographed dance to create an upside-down fountain effect. Illuminated water falling down from the sky and blending with the water coming up from the ground basedfountains 510 may create a very exciting and dramatic water display. - It should be noted that during water feature performances, it is often desirable to clear fog from the water surface and from other areas around water streams in order to allow better viewing of the display. In another embodiment of the current invention,
UAS 10 may be configured to direct the generally downward stream of air that is created by its propellers 16 (often referred to as downwash or propwash) onto the water surface, into areas aroundwater streams 512, or to other areas, to clear any undesired fog or mist that may exist. To this end,UAS 10 may include air rudders, channels, or other guide structures that may direct its propwash in a desired and controllable direction.UAS 10 may then be positioned such that its propwash may disperse fog or mist fromwater display 500 as necessary. - In addition, if the propwash of
UAS 10 is not sufficient to clear the water display of undesired fog or mist,UAS 10 may be configured with an additional fan or air blower unit that may achieve the desired result. - Furthermore, the propwash from
UAS 10 or the air stream from an additional air blower unit may be used to reshapewater streams 512 mid-air, creating new shapes of blown water and mist. In one example, fourUASs 10 positioned in equal quadrants aroundvertical water stream 512 may each channel air streams intowater steam 512 at a slightly upward angle in order to create upward shooting spikes of water and mist resulting in a “floating crown”. - In another embodiment,
UASs 10 may be configured with cameras and memory units to record and save images and video footage ofwater display 500 from perspectives and vantage points previously unattainable.UASs 10 may also be configured with broadcast units to transmit recorded images or video to a ground station which may project the footage onto a screen or relay it to a large video monitor (such as a Jumbotron) to be viewed by an audience. Or,UAS 10 may have the ability to bypass ground station and broadcast recorded footage directly to a video monitor equipped with a receiver unit to display the footage to the audience in real time. In addition, footage fromUAS 10 as described above may also be broadcast on the Internet in real time for audiences around the world to view. In one example,UAS 10 configured with a camera, memory and broadcast capability may position itself directly abovewater display 500 while recording and broadcasting its footage. Video footage from this vantage point may then be displayed in real time onto a large screen that is viewable to the audience ofwater display 500, as well as broadcast on the Internet to a global audience, thus giving both audiences a never before seen top-down perspective ofwater display 500. It can be seen that such video footage or still images may also be recorded and stored for future viewing by similar or different audiences. - Although certain presently preferred embodiments of the invention have been described herein, it will be apparent to those skilled in the art to which the invention pertains that variations and modifications of the described embodiments may be made without departing from the spirit and scope of the invention. It is intended that the claims herein be interpreted to cover any such modifications. It is further intended that the present invention be not limited according to any particular disclosed embodiment, but rather only according to the appended claims.
